You mean well, but you are incorrect, and probably just repeating what you have been told.
There was a very good reason I suggested THAT antenna.
It is because it is a 1/4 wave ground plane, with sloping radials, that feeds through it's support pipe.
W8JI has computer modeled these types of antennas, and found they are FAR superior to end fed antennas, if low angle gain on the horizon is what you are after.
This is because these types of antennas are free of the common mode issues that plague most end fed vertical CB Antennas.
Some of the end fed antennas W8JI Modeled showed as much as -8 DB Gain, at low angles!
Think you might notice 8 db of gain ?
ROFLMAO. I've modelled them. There is no way in hell a 1/4 wave groundplane is going to be 8dB better than a halfwave. Not ever. It is standard antenna theory that the maximum gain lobe of a 1/4 wave groundplane is at a higher angle than a half wave or longer and that on lower angles it doesn't compete.
I'm not repeating what I'm told, I'm repeating 100+ years of antenna theory and actually modelling them myself.
The fact you think its not an end-fed vertical "because its fed through its support pipe" proves just how little you actually know.
-8dB is loss. An antenna that has 0dB doesn't have gain even though its 8dB up on a -8dB antenna.
It is impossible no matter where you want to feed a single element monoband antenna to have 8dB gain unless you start going into co-linears.
